Threat metrics

Exploit Maturity: POC

Bold values are the worst case: easiest to exploit or largest impact.

Attack Vector: Network: The vulnerable system is bound to the network stack and the set of possible attackers extends beyond the other options listed below, up to and including the entire Internet. Such a vulnerability is often termed “remotely exploitable” and can be thought of as an attack being exploitable at the protocol level one or more network hops away (e.g., across one or more routers).
Attack Complexity: Low: The attacker must take no measurable action to exploit the vulnerability. The attack requires no target-specific circumvention to exploit the vulnerability. An attacker can expect repeatable success against the vulnerable system.
Attack Requirements: None: The successful attack does not depend on the deployment and execution conditions of the vulnerable system. The attacker can expect to be able to reach the vulnerability and execute the exploit under all or most instances of the vulnerability.
Privileges Required: None: The attacker is unauthorized prior to attack, and therefore does not require any access to settings or files of the vulnerable system to carry out an attack.
User Interaction: None: The vulnerable system can be exploited without interaction from any human user, other than the attacker.
Vulnerable system confidentiality: Low: There is some loss of confidentiality. Access to some restricted information is obtained, but the attacker does not have control over what information is obtained, or the amount or kind of loss is limited. The information disclosure does not cause a direct, serious loss to the Vulnerable System.
Vulnerable system integrity: Low: Modification of data is possible, but the attacker does not have control over the consequence of a modification, or the amount of modification is limited. The data modification does not have a direct, serious impact to the Vulnerable System.
Vulnerable system availability: Low: Performance is reduced or there are interruptions in resource availability. Even if repeated exploitation of the vulnerability is possible, the attacker does not have the ability to completely deny service to legitimate users. The resources in the Vulnerable System are either partially available all of the time, or fully available only some of the time, but overall there is no direct, serious consequence to the Vulnerable System.
Subsequent system confidentiality: None: There is no loss of confidentiality within the Subsequent System or all confidentiality impact is constrained to the Vulnerable System.
Subsequent system integrity: None: There is no loss of integrity within the Subsequent System or all integrity impact is constrained to the Vulnerable System.
Subsequent system availability: None: There is no impact to availability within the Subsequent System or all availability impact is constrained to the Vulnerable System.
Exploit Maturity: POC: Based on threat intelligence sources each of the following must apply: · Proof-of-concept is publicly available · No knowledge of reported attempts to exploit this vulnerability · No knowledge of publicly available solutions used to simplify attempts to exploit the vulnerability

Exploitation evidence

Disclosed: evidence found.
CVE published 29 Jan 2026
Detectable: no evidence on record.
No public nuclei template indexed
Weaponised: no evidence on record.
No public exploit code indexed in Metasploit or Exploit-DB
Exploited in the wildExploited: no evidence on record.
Not in CISA KEV and no source reports exploitation
Observed by OffSeq MirageSeen by Mirage: no evidence on record.
No attack traffic recorded by OffSeq Mirage sensors

A missing step is not evidence of safety. Sources: cve.org (opens in a new tab), the Metasploit, Exploit-DB and nuclei-templates index as of 2026-10-26.

Disclosed: The CVE record is public on cve.org. Its publication is t = 0.
Detectable: A public nuclei template can find exposed instances, for defenders and attackers alike.
Weaponised: Public exploit code exists in Metasploit or Exploit-DB, or CISA SSVC reports a public proof of concept.
Exploited in the wild: CISA KEV lists it, CISA SSVC rates exploitation active, or a source reports attacks.
Observed by OffSeq Mirage: OffSeq Mirage honeypot sensors recorded attack traffic for this CVE, or found exposed hosts without attack traffic.

Moments are spaced evenly, not to scale; a dashed line marks a gap of six months or more. Deltas count from t = 0. Sources that give only a date (CISA KEV, Exploit-DB, or a time of exactly 00:00Z) read “same day” rather than hours. Metasploit modules carry the flaw’s disclosure date, not their release date, and nuclei templates carry no date, so both appear above but not on the timeline.

AI-suggested

To mitigate CVE-2026-1589, organizations should first seek any official patches or updates from itsourcecode; if unavailable, immediate steps include implementing strict input validation and sanitization on the txtsearch parameter to prevent injection of malicious SQL code. Employing parameterized queries or prepared statements in the application code is critical to eliminate direct concatenation of user inputs into SQL commands. Web application firewalls (WAFs) can be configured to detect and block SQL injection attempts targeting the vulnerable endpoint. Regularly monitoring logs for suspicious query patterns or unusual database activity can help detect exploitation attempts early. Network segmentation and restricting access to the school management system to trusted IP ranges can reduce exposure. Additionally, conducting security code reviews and penetration testing focused on injection flaws will help identify and remediate similar vulnerabilities. Backup strategies should be enforced to ensure data recovery in case of compromise. Finally, educating developers on secure coding practices will prevent recurrence of such vulnerabilities in future software versions.

Description

A vulnerability was determined in itsourcecode School Management System 1.0. This affects an unknown function of the file /ramonsys/inquiry/index.php. This manipulation of the argument txtsearch causes sql injection. The attack can be initiated remotely. The exploit has been publicly disclosed and may be utilized.

Impact

The exploitation of this SQL Injection vulnerability can lead to unauthorized access to sensitive student and institutional data, including personal information, academic records, and administrative details. Attackers could manipulate or delete data, compromising data integrity and availability of the school management system. This could disrupt educational operations, damage institutional reputation, and potentially violate data protection regulations. Since the vulnerability is remotely exploitable without authentication, it broadens the attack surface, allowing attackers to target vulnerable systems over the internet. The impact extends to confidentiality breaches, data tampering, and possible denial of service conditions if database integrity is compromised. Organizations relying on this software may face operational downtime and legal consequences if sensitive data is exposed or altered. The medium severity rating reflects a significant but not catastrophic risk, emphasizing the need for timely mitigation to prevent escalation.
